            This function is used to write data to the serial port. The function
            call will block until one or more bytes of the data has been written
            successfully, or until an error occurs.

            The write_some operation may not transmit all of the data to the peer.
            Consider using the <a class="link" href="../../write.html" title="write"><code class="computeroutput">write</code></a>
            function if you need to ensure that all data is written before the blocking
            operation completes.
